#define MACE_STUB	(		NAME,
			MEMBERS
	)		MACE_STUB_DERIVED( NAME, BOOST_PP_SEQ_NIL, MEMBERS )

Note:

Must be used at global scope.

Parameters:

NAME	a fully qualified class name.
MEMBERS	a sequence of member methods on NAME ie: (method1)(method2)(method3)...

#define MACE_STUB_DERIVED	(		NAME,
			INHERITS,
			MEMBERS
	)

Value:

namespace mace { namespace stub { \
template<typename InterfaceDelegate > \
struct vtable<NAME,InterfaceDelegate> : BOOST_PP_SEQ_FOR_EACH( MACE_STUB_VTABLE_PUBLIC_BASE, InterfaceDelegate, INHERITS ) private vtable_base<NAME> { \
    typedef NAME interface_type; \
    typedef InterfaceDelegate delegate_type; \
    BOOST_PP_SEQ_FOR_EACH( MACE_STUB_VTABLE_DEFINE_MEMBER, NAME, MEMBERS ) \
}; \
template<typename InterfaceDelegate> struct vtable_reflector<NAME,InterfaceDelegate> { \
    typedef NAME interface_type; \
    template<typename Visitor> \
    static void visit( const Visitor& visitor ) { \
        typedef mace::stub::vtable<NAME,InterfaceDelegate> vtable_type; \
        BOOST_PP_SEQ_FOR_EACH( MACE_STUB_VTABLE_VISIT_BASE, visitor, INHERITS ) \
        BOOST_PP_SEQ_FOR_EACH( MACE_STUB_VTABLE_VISIT_MEMBER, visitor, MEMBERS ) \
    } \
};\
\
} }

Note:

Must be used at global scope.

Parameters:

NAME	a fully qualified class name.
INHERITS	a sequence of fully qualified base classes that NAME inherits from ie: (method1)(method2)(method3)...
MEMBERS	a sequence of member methods on NAME ie: (method1)(method2)(method3)...
